SUMMARY Pixel Art brush cursor Locks into Pixel Grid. Looks and feels unresponsive to tablet strokes when using freehand drawing. Leads to inaccurate drawing when using Free Hand Brush Tool. STEPS TO REPRODUCE 1. Use the default "u)_Pixel_Art*" brushes 2. Move the pen/mouse around the canvas using Freehand Brush tool. 3. Draw using Freehand Brush tool. OBSERVED RESULT Brush Cursor locks into pixel grid and does not accurately respond/move with pen strokes resulting in inaccurate freehand drawing. EXPECTED RESULT Center of brush cursor should be in center of pointer and moves with pen.

I'm sorry that you don't like this, but it's intentional. See https://bugs.kde.org/show_bug.cgi?id=407405 and the following commit: If you want to avoid things like this, you'll have to participate in the discussions that drive Krita's development and test nightly builds and beta's. commit 9a972eea69526311cd95dd45335d2f1ba7d24fc3 Author: Ivan Yossi <ghevan@gmail.com> Date: Wed Dec 4 07:51:59 2019 +0000 Fix 1px brush offset in line tool This adjust the diferent position of KisPaintInformation from a line to be inside a line between starting and ending points. This is particularly important as brushes that use 1px perfect pixels require the line to be perfect in order to avoid looking jagged. In 1px size with sharpen active we only use the start and end KisPaintInformation points. This patch also adjusts the outine on 1px brushes to adjust to the grid to better preview where the paint is going to be applyied BUG:407405 (cherry picked from commit b434751233e91d229617952bb73ca0744353bd10)

[19:42:13] <tiar> dmitryK|log: not sure if it's a bug, but certainly a complaint. https://www.reddit.com/r/krita/comments/fp7xaq/pixel_art_brush_cursor_pixel_lock/flkqal6/?context=3 [19:42:53] <dmitryK|log> tiar: the screenshot looks really buggy [19:43:43] <tiar> dmitryK|log: should I tell them to file a bug report? [19:44:07] <rebecca2525> buggy how? [19:45:05] <ivanyossi|log> rebecca2525: the outline should be on the pixel grid not inbetween the pixels. [19:46:12] <rebecca2525> Oh, I was looking at the wrong screenshot [19:50:45] <Lynx3d> hm I cannot reproduce the pixel brush outline not matching the pixel grid, but the outline does seem to jump to the next pixel before the brush actually draws there... [19:54:57] <dmitryK|log> Lynx3d: make sure 1) you activate sharpness; 2) when you click, the brush paints exactly at the place where the outline is [20:05:12] <dmitryK|log> Lynx3d: did you manage to reproduce the pixel-brush bug in the end? [20:09:30] <Lynx3d> dmitryK|log, not really, while it's different that the outline now snaps to pixels, I don't have any misalignment, only that the dab draws a bit later than the actual outline jump occurs
Okay, let's reopen then, though I still think that the new behaviour when sharpen is enabled is actually preferable.
